[Dark Knight]

What heads are you running? Are you running guide plates? If they're the early heads with the pushrod slots and you're running guide plates, the might be binding the pushrods..

Also, check the clearance from the underside of the valve spring retainer to the top of the valve guide.

If the exhaust valves were hit hard enough to bend the pushrods, it would bend the valves too, I would think. Compression test would show it..
